IS my jetting as good as it gets

Ok I am running the LarryCo jetting here in Colorado (38PJ 1.5 turns 65PAJ EKP#3 150MJ 160MAJ) (6K-10Kft) This jetting seems to be awsome in comparison to how the dealer had it set up. However since then I have added a power now and an WB R4 exhaust. I am just wondering if that is the rite jetting for the changes I have made.

Part two I am thinking this weekend I will change my timing to YZ timing. What do I do with the Jetting then???

Just a side note that I am not to concerned with but thought that I would throw it out there. My head pipe has turned purple all the way to the heat sheild?? I know of two other guys I ride with, with the same jetting and they are not getting any discoloration on there pipes.

With the other modifications that you have made (Power now and WB exhaust) do you notice and stubbles or changes from adding the new parts? I think Wicked Crash out here is running a EKQ needle and a PJ 38 with the Power Now and loves the jetting he has come up with.

You know what I have to be honest!! I did notice a diffrents with the power now in it. It does pull alot harder on the bottom end. I mean we went to Rampart last week and I had the pleaser of desiding where to put the front end down over the whoops. It use to be one of those just hold on for dear life things. That was alot of fun. So would I tell you to get one. Yes so lond as you are not trying to get rid of a bog all together. It helps but it does not get rid of the off idle bog altogether.

The Exhaust does seem to let it rev faster. The one thing that I will have to get use to is that there is no back presure now and when going down hills gearing down to use the compresion to slow you down does not work real well. I have to use the brakes a ton more. It is loud though. But the way I figure, it must not be to loud because we saw some Deer about 50 yards away and I reved it up a few times and they just looked at me. Whatever.

Hick thanks for the help but let me ask you this. For rampart I would agree that the EKQ would most likely be better. What would happen though if I go to 10-14 thousand feet?? That is where I like to ride but I am not the type of person that is going to change jets half way up the mountain. I am looking for a combo that will work at rampart and 14 thou. Is there such a thing??? If so what??? Thanks for you input.

Since it is leaner than the EKP, the EKQ should work above 10,000 ft. I have had really good luck with my jetting. I will hopefully get to test it above 10,000 ft pretty soon. I'm not sure how the EKQ will work for you though since you have an aftermarket exhaust, you might need to stay with a richer needle like the EKP.

Arvada is just north west of Denver. Basicily Denver.

Well, if you wanted to go Rampart and higher, I would say EKR # 2, and try clip # 1.
